Claims.

This invention relates to a facing and a method of securing the same to a support and is a companion application to our application filed December 18, 1936, Serial Number 116,604, the object being to utilize heat generated by electrical energy to volatilize or evaporate the volatile substances of an adhesive material used for securing two or more members together, whereby the setting of the adhesive material is accelerated so as to secure the members firmly together quickly, thereby overcoming the difficulties now existing of depending on atmospheric conditions to carry oif the volatile substances of the adhesive material.

In carrying out our invention we utilize electrical energy to heat and volatilize the volatile substances from a. relatively normally plastic adhesive material to change the characteristics of the adhesive material to cause the members to so be more rigidly secured together, the object being to provide a method which allows the initial use of a normally plastic adhesive material in securing two or more members together to allow for the proper positioning of the members on an uneven surface and yet allow the members to be rigidly set quickly by changing the characteristics of the adhesive material from a normally plastic I adhesive material to one which will set relatively hard in a verylshort time.

Our invention is particularly adapted for securing flooring units to a support with a normally plastic mastic which can be applied on the support or betweenthe support and members or carried by the members to be secured to the support 5 and has embedded therein or in contact therewith or in proximity thereto a resistance material to form a conductor of electric current in order to generate sufficient heat when electric current i is passed therethrough to volatilize or partly o volatilize the volatile substances of the adhesive material to increase the adhesiveness of the ad hesive material to cause the same to more quickly and firmly secure the members together after being positioned.

Another way of carrying out our method is to apply at the factory to the inner face of the facing a normally plastic adhesive material protected if desired by any suitable means to prevent it from sticking in shipping and embed therein or arrange in close proximity thereto a resistance material which will extend outwardly beyond the edges of the facing so as to overlap and make electrical contact with the outwardly extending portions of the resistance material of the adjacent facing whereby the facing could be laid on or against a support and electric current passed through the resistance material to dry the adhesive material to quickly secure the facing to the support.

Another way of carrying out our invention of securing a facing to a support is to arrange sheets of adhesive material which maybe reinforced by paper or fabric to each side 'of the resistance material and dry the adhesive material by passing an electric current through the resistance material to cause the facing to be quickly secured to a support.

Our invention consists broadly in securing two or more members together by quickly drying an adhesive material through the medium of a resistance material arranged in contact with the adhesive material and while we are aware that this can be accomplished in various ways, we do not wish to limit ourselves to any form of apparatus or any particular manner of carrying out the broad idea of quickly drying normally plastic adhesive material by passing an electric current through a resistance material for evaporating moisture and volatile substances.

The invention disclosed in this application is substantially the same in all respects to that disclosed in our companion application and utilizes a similar apparatus for carrying out a new method of securing two or more members together by a relatively normally plastic or tacky adhesive material by evaporating or volatilizing the volatile substances of the adhesive material to cause the material to set quickly and we wish it to be clearly understood that this method can be used with any and all of the disclosure of our companion application by substituting a relatively normally plastic or tacky adhesive material for what has been termed a relatively non-tacky adhesive material and this application is only filed to make a clear line of division between the two methods as applicants recognize the similarity of the two inventions as the moisture in and about the members to be secured together is removed by evaporation at the same time that the nature of the adhesive material is changed.

We have described in this application the removal of moisture from the members to be connected as well as the removal of thevolatile substances of the adhesive material as moisture and solvents are expelled by the heat generated by the heating of the resistance material which when in foraminous form aids in venting the vapors produced by the drying of the adhesive material and the members to be connected.

Other and further objects and advantages of ment in the form of a block which is to be used for flooring having an adhesive material and a resistance material carried by the underside thereof;

Figure 3 is a perspective view of a sectional flooring composed of a plurality of sections arranged on a foraminous base of resistance material and secured thereto by adhesive material and which is also coated on its under side so that when heated bypassing an electric current through the foraminous base, it will be quickly secured to a. support;

Figure 4 is a detail perspective view, partly broken away, of a panel showing a core enveloped in a metal casing of resistance material coated with an adhesive material against which is arranged veneer so that when an electric current is passed through the envelope of resistance material and pressure is applied to the outer' facing 1 of veneer, the veneer will be secured to the resistance material and the resistance material to the core to form quickly a strong fireproof unit; and

sheets being preferably turned up adjacent the walls as shown. 7 The flooring elements I, either in strip, block or sheet form are then laid over the previously laid sheets of resistance material and after the flooring has been positioned an electric connection along the edges of the sheets is made by contact strip 5 with an electric apparatus 6 connected to a sourceo'f electrical energy so as to cause an electric current to pass through the resistance material to heat the same which will volatilize the volatile substances of the adhesive material and by applying pressure, if necessary, to the upper surface of the previously laid flooring, the flooring will be set and secured to the subfloor by the adhesion of the adhesive material very quickly and when the electric apparatus is disconnected, the flooring will be firmly set so that all danger in the future of the adhesive material being activated by ordinary temperature is prevented and we are able to lay a flooring in this manner very quickly without any danger of the flooring being discolored by the adhesive material used for binding the same to the subfloor working up between the flooring unit. I

the facing is in position thereon in order to bind the facing thereto is only given as one of the many ways that our method of securing a facing ofany kind to a support by utilizing electrical energy for drying a relatively tacky adhesive material and therefore we do not wish to limit ourselves to any particular kind or form of normally plastic adhesive material, kind or form of resistance material, or any particular construction of apparatus for passing electric current through the resistance material.

While in Figure l we have illustrated a flooring formed of a plurality of blocks, we are aware that the members forming the'flooring elementv can be formed of any shape desired and may be in the form of strips, blocks or sheets and that our invention is not limited to wood flooring as tile constructed of various material can be laid in accordance with our invention.

In Figure 2 of the drawing we have illustrated a wood block flooring element formed of a pluployed without interlocking features and can a carry a normally plastic adhesive material which can be protected by any suitable means, as.for example Cellophane, oil paper or a powder so as to allow a block so constructed to be manufactured at the factory and shipped without the blocks adhering to one another.

To the under side of this block I we secure at the factory a sheet of resistance material 8 by adhesive material 9 which is coated-on its under surface by adhesive material In and when these blocks are laid with their edges abutting one another, the outwardly extending portions of the sheet of resistance material will make electrical connection with the adjacent sheet of resistance material carried by the adjacent block so that when a plurality of these blocks are assembled to form a floor or the like, means is provided for making an'electrical connection with any number of .these' blocks so that when a current of electricity passes through the resistance ma-,

terial, the adhesive material will be dried so that by applying pressure, if necessary, to the upper surface of the block it will be firmly set on the subfloor' or support as the case may be and while we are'aware that in the drying of the adhesive material on the under side of the resistance material, that the adhesive material on the upper surface of the resistance material which secures the resistance material to the block will be dried, this allows the adhesive material to be in a plastic state so that the blocks will quickly set themselves when pressure is applied so as to form a smooth and even surface of flooring. In this form of block we have illustrated a solid sheet of resistance material 8, but we are aware that this resistance material can be in any'form for example, bars, sheets, or wire or particles to conduct the. electric current.

In Figure 3 of the drawing we have illustrated a portion of a section of flooring composed of a plurality of blocks ll arranged on a foraminous base l2 and secured thereon by adhesive material l3, which carries adhesive material II on its under surface so that when a section of flooring which has been manufactured at the factory, is laid on a support or against the same and an electric current is passed through the resistance material, the adhesive material will be dried in order to allow the section to be securely fastened to the support by the adhesive material and while in the drawing we have only shown a portion of a section so constructed, we do not wish to limit ourselves to any particular size of section nor to the shape or kind of facing forming the flooring elements carried by the base as we are aware that this construction of section very quickly after the same has been positioned 'our invention.

on the support to which it is to be secured by passing an electric current through the resistance material and while we have shown a simple form of facing with means for making an area than the facing as additional means could a be employed for making an electric connection.

between the resistance material of one section and another without departing from the spirit of In Figure 4 we have shown as a new articleof manufacture a panel l5 consisting of a core l6 which is enveloped by a metallic casing of resistance material or the like I! which has disposed-between its inner face and the core a sheet of adhesive material l8 and between its outer face and the veneer facing l9 a sheet of adhesive material and by passing an electric current through the resistance material, the adhesive material will be dried and by applying pressure to the outer facing of the veneer, a complete panel can be manufactured very cheaply.

In Figure 5 we have shown the normally plastic adhesive material protected by means 2| to prevent the same from sticking in shipping or when applying the facing element.

In the drawing and description thereof we have only illustrated and described a few ways of carrying out our method of securing a facing to a support, but we are aware that this method can be used in a great many arts where it is desired tosecure a facing to a support by adhesive material and therefore we do not wish to limit ourselves to the nature of the facing or the nature of the support.

In the specification we have used the term facing generically to indicate a covering of any kind in strip, block or sheet form of any kind of material for building purposes, as for example, a facing for walls, ceiling and floor of a room or outside covering of a building, such as the roofing and wall facing or the production of an article of manufacture, as for example, doors, trim, columns, or articles of furniture.

a facing to a support, we wish it to be clearly understood that the word facing does not necessarily mean an outer facing as our invention can be used for securing two or more members together whether said members form the outer facing or the interior portion of any structure.

In the specification we have used the term resistancetmateria to indicate any kind or form of material which will ofier a sufficient amount of resistance to the passing of an electric current to heat the adhesive material in order to dry the same so that the facing will be secured to the support after it has been applied thereto and this material may bein any form, for example,

While our invention is particularly adapted for securing bars, sheets, wire or particles to conduct the electric current.

While in the specification 'we have set up several ways of carrying out our method of securing a facing to a support, .we are aware that various other ways of using the broad principle of heat generated by electrical energy to dry the adhesive material can be used, and we do not wish to limit ourselves to the examples given in any way as our invention consists broadly in quickly drying an adhesive material by electrical energy for binding two or more members together whether metallic or non-metallic. As various forms of apparatuses for carrying out our invention can be used as the apparatus only consists of means for passing an electric current through a resistance material, we have only illustratcd a simple form of apparatus for carrying out our method and while it may be possible to pass an electric current through an entire floor surface of a room, in some instances it may be advisable to only pass an electric current successively through sections of the surface area as the facing is-laid, therefore, we reserve the right to use electrical energy in the broadest possible way for drying the adhesive material for securing two or more members together used for any purpose desired.

In the specification we use the term normally plastic adhesive material which is relatively tacky to indicate an adhesive material which is plastic under normal atmospheric conditions and wish it to be clearly understood that we do not limit ourselves to any particular kind of adhesiv material as the application of heat generated by the resistance material will be governed by the nature of the resistance material, the nature of the adhesivematerial and the time of the application of electrical energy so as to dry the adhesive material by volatilizing til: volatile substances thereof.

While in the disclosure of carrying out our method to form a panel we have failed to show any means for venting the vapors generated by the heating of the resistance material, we wish it to be clearly understood in carrying out our invention in any of the various ways, means can be provided for venting the vapors driven off so as to allow the same to readily escape and when laying a flooring the use of a foraminous resistance material would allow the venting of the vapors and when a sectional facing element is employed, the vapors escape between the abutting edges of these elements. This application is a companion application of our application filed December 18, 1936, and we have failed to describe all of the various examples and methods set up therein but the method described therein is capable of being used in all of the examples set up in our companion case.

In carrying out our method when using a metal support to which a facing element is adapted to be secured by adhesive material, we utilize a metal support as a resistance material through which we pass an electric current for changing the characteristics of the adhesive material so that the same is set quickly.

In all of the ways of carrying out our method we volatilize the volatile substances from a normally plastic adhesive material so as to increase the adhesiveness quickly as our method enables securing together two or more surfaces by normally plastic adhesive material in the matter of minutes or hours by the use of heat generated by material.

While we have found that good results can be obtained with a resistance material for heating and drying the adhesive material which remains in its original condition after the electric current haspassed therethrough, we are aware that a sufficiently high electric current could be passed through a specific kind of resistance material to volatilize or decompose the resistance element so that the gases and ash combine with the adhesive material either chemically or as a mechanical mixture or in the case of gase pass off and therefore we do not wish to limit ourselves to the nature of the resistance material so long as the resistance material will offer the required amount of resistance togenerate sufllcient heat to carry out the partly or wholly drying of the adhesive material.

In the specification and claims we have used the term a relatively tacky adhesive material to indicate an adhesive material which is sticky at the time of its application or has been made sticky after its application by a solvent which will be wholly or partly evaporated by the heat generated by the passing of an electric current through the resistance material so as to change the characteristics of the same to meet the desired requirement as the adhesive material may remain normally plastic or may become hard which will depend partly or wholly on the nature of the adhesive material and partly or wholly on the degree of heat and the time of its application and while we have selected the term normally plastic adhesive materia, this is used generically and our method is capable of being used with any and all kinds of adhesive material and cements to change the characteristics of the adhesive material and cement.'

The adhesive material may be in dry form and moistened to make it tacky by adding water thereto and our invention consists broadly in evaporating the volatile substances from the adhesive material to make it set.
